Table of Contents


  • Various models: LLaMA, LLaVA, Mistral, Mixtral-MoE, Qwen, Yi, Gemma, Baichuan, ChatGLM, Phi, etc.
  • Integrated methods: (Continuous) pre-training, (multimodal) supervised fine-tuning, reward modeling, PPO, DPO, KTO, ORPO, etc.
  • Scalable resources: 32-bit full-tuning, 16-bit freeze-tuning, 16-bit LoRA and 2/4/8-bit QLoRA via AQLM/AWQ/GPTQ/LLM.int8.
  • Advanced algorithms: GaLore, BAdam, DoRA, LongLoRA, LLaMA Pro, Mixture-of-Depths, LoRA+, LoftQ, PiSSA and Agent tuning.
  • Practical tricks: FlashAttention-2, Unsloth, RoPE scaling, NEFTune and rsLoRA.
  • Experiment monitors: LlamaBoard, TensorBoard, Wandb, MLflow, etc.
  • Faster inference: OpenAI-style API, Gradio UI and CLI with vLLM worker.


Compared to ChatGLM's P-Tuning, LLaMA Factory's LoRA tuning offers up to 3.7 times faster training speed with a better Rouge score on the advertising text generation task. By leveraging 4-bit quantization technique, LLaMA Factory's QLoRA further improves the efficiency regarding the GPU memory.


  • Training Speed: the number of training samples processed per second during the training. (bs=4, cutoff_len=1024)
  • Rouge Score: Rouge-2 score on the development set of the advertising text generation task. (bs=4, cutoff_len=1024)
  • GPU Memory: Peak GPU memory usage in 4-bit quantized training. (bs=1, cutoff_len=1024)
  • We adopt pre_seq_len=128 for ChatGLM's P-Tuning and lora_rank=32 for LLaMA Factory's LoRA tuning.

Docker image:

Remember to use ASCEND_RT_VISIBLE_DEVICES instead of CUDA_VISIBLE_DEVICES to specify the device to use.

If you cannot infer model on NPU devices, try setting do_sample: false in the configurations.

Data Preparation

Please refer to data/ for checking the details about the format of dataset files. You can either use datasets on HuggingFace / ModelScope hub or load the dataset in local disk.


Please update data/dataset_info.json to use your custom dataset.


Use the following 3 commands to run LoRA fine-tuning, inference and merging of the Llama3-8B-Instruct model, respectively.

llamafactory-cli train examples/train_lora/llama3_lora_sft.yaml
llamafactory-cli chat examples/inference/llama3_lora_sft.yaml
llamafactory-cli export examples/merge_lora/llama3_lora_sft.yaml

See examples/ for advanced usage (including distributed training).

    --shm-size 16G \
    --name llamafactory \

Use Docker Compose

docker-compose up -d
docker-compose exec llamafactory bash
Details about volume
  • hf_cache: Utilize Hugging Face cache on the host machine. Reassignable if a cache already exists in a different directory.
  • data: Place datasets on this dir of the host machine so that they can be selected on LLaMA Board GUI.
  • output: Set export dir to this location so that the merged result can be accessed directly on the host machine.

Deploy with OpenAI-style API and vLLM

API_PORT=8000 llamafactory-cli api examples/inference/llama3_vllm.yaml

Download from ModelScope Hub

If you have trouble with downloading models and datasets from Hugging Face, you can use ModelScope.

export USE_MODELSCOPE_HUB=1 # `set USE_MODELSCOPE_HUB=1` for Windows

Train the model by specifying a model ID of the ModelScope Hub as the model_name_or_path. You can find a full list of model IDs at ModelScope Hub, e.g., LLM-Research/Meta-Llama-3-8B-Instruct.

Use W&B Logger

To use Weights & Biases for logging experimental results, you need to add the following arguments.

report_to: wandb
run_name: test_run # optional

Set WANDB_API_KEY to your key when launching training tasks to log in with your W&B account.
